Help finding correct piece to window lock

A home owner from USA says:
Hi, I really need help finding our window lock piece that the lock latches onto to keep it shut. I can't find it at Home Depot or Lowe's unfortunately. I could really use help! Thanks in advance

Hello,

Unfortunately, we do not carry this exact keeper but you could consider the 90-301 or 90-283 are two possibilities. Keep in mind that we can't guarantee that either would work since the 90-301 might be too short, while 90-283 might be too tall. If you need the sash lock as well, see the 90-309. Thanks for posting!
